The Studio Vu, alone, utilizes a 75x75mm and 100x100mm VESA pattern. The universal adapter plate, designed for the Studio Vu, accomadates larger monitors, up to 36kg, that extend beyond the 200x200mm and 400x200 VESA patterns. For example, if a 400x400 pattern is needed, use the universal adapter in conjunction with the 200x200 Bracket Adapter.
